Just to continue the Christmas games theme…
The weather clap clap game is a great way to practice any theme that has a question + answer approach. But for the Genki Christmas theme there isn’t a question! So instead try chanting “Christmas, Christmas, ho, ho, ho!”, then everyone mimes ( and says ) either the Christmas tree, Santa, presents or reindeer. Anyone who has the same gesture as the teacher is out and sits down!
Not the most useful English practice, but a nice bit of Christmas fun.
Thanks to the other Craig in Fukuoka for the chant!
